To all whom it may concern 1 Be it known that I, PEARLVD. KARSHNER, a citizen of the United Kansas C ity, in the county of Jackson and, State of Mis'souri, have invented certain new and useful Improvements in Speed-Regu- T lators; and I do declare the followingto be;

. use the same, reference being had to the ac- I I 'of the'carbureter and its .45

provide means for'controlling fuel in order that the spec l'designates engine cylinders,

a full, clear and exact description of the ini vention, such as :will enable others skilled in the art to which it appertains to make and;

companying drawings, and to the letters and figures of reference marked thereon, whichi form'a part of this specification. I

My invention relates to a regulator .for vapor engines and more particularl to a device for'automatically regulating t e discharge of a fluid fuel medium from a carbureter to the cylinders of such an engine, for thepurpose of limiting the fuel supply in order to-prevent the vehicle, which is driven by such engine, from, traveling at greater than a predetermined speed. I

Itis a further object of my invention to the supply of at which thei vehicle may be driven may 'be determined by the operator. In accomplishing, this obj ect I have provided the improved details of structure hereinafter described and illus-;' trated inthe accompanying drawings, in lwhich Y I Fi re I is;a perspective view'of the hood and dd sh of an automobil provided with a regulator constructed according to my invention, a part of the hood being removed to illustrate the arrangement of the regulator and its connection with the carbureter. Fig. II .is an enlarged elevational view of the governor mechanism. Fig. III is a longitudinal section of'same, Fig. IV is a cross section on'the line IV-IV, Fig. IL Fig. V is a detail view of a part I supply valve. Fig. VI is a detail view of a portion of the quad-- rant and regulating lever. I

Referringmore m detail to'the parts 2 a carbureten'. 3 vapor conduits eading from the carbureter to the cylinders, 4 a supply tube leading to the-carburetor, 5 ,a steering post havinga lever 6 for controlling the vapor supplyand '7 an engine cam shaft, all of which parts may be of ordinary. construction.

States, residing, at

e having an engine I dicate On the engine base 8 is a tubular boss 9, and seated on said boss is a post 10 having a flange 11 at its upper end, and a central. stud 12 having an inset pin 13, the upper portion-of which is screw threaded. Flxed v to the base of post 10 is a pin 14 which extends downwardly through the boss 9 and carries a beveled gear 15 which meshes with agear 16 on the cam shaft7. Seated on the shoulder of stud 12 and surrounding the pin 13 is a spring'1(, and stud is a cup 18, the 'snugl against, but is adapted for revoluble fitting over the pin and lower end of which fits and siding movement on the stud 12, ahd

has a flange 19 of diameter as the post the cup is apertured so that pin 13 may project therethrough and is supported on the spring 17, so that the flange 19 isyieldingly spaced from the flange 11. Interposed etween the 'fianges 11 and 19 is a ring. 20 having upper and lower faces 21 of fiber, or other friction inducing spaced above the upper ring face and out of end of pin 13 is a cap 22 having a flange 23 at its lower end, provided with depending paired lips 24 which extend downwardly I at the sides of the cap body 18 and are adapted for engaging a flange 18' thereon,to revent'the cap flange from turning arou'n "the cup.

substantially the same flange 11. The top of" I material, the spring 7 17 bemg adapted for holding the cup ange SeeFig. IV. Ears 24 carry pins 25 and pivotally mounted on said pins are the governor arms 26 having weights 27 at their outer ends and having lips 28 at their inner ends; said lips being located above the top of the cup and adapted for impingement thereagainst when the governor weights are lifted by centrifugal force. end of pin 13' is a lock-nut 29for holdingthe cap 22 in lace. Ring 20 is provided with a lug 3O WlllCh is pivotally connected with a rod 31 which extends back toward the dash and is operatively corinected with a valve not'shown on the car ureter 2, through a link 32.

On the upper 33 designates'a quadrant which is prefer ably mounted on the dash of the vehicle and has notches 34: which are graduated and invarious road speeds. Pivotally mounted adjacent to the quadrant, preferably on a web 35 thereof, is -.a 'bell'crank lever 36, one arm of'which has a tooth 37 device (not shown),

for taking into the quadrant notches and is provided with a knob 38. Connected with the other arm of lever 36 is one end of a spring 39, the opposite end of which is connected with the carbureter rod. 31, preferably through a mounting 40.- The carbureter rod is also connected with the lever '6 on the steering mechanism by a suitable but indicated by the crank 41. Prior to installation of the regulator, the parts thereof may be adjusted, relative to the motor, so that the spring tension will resist the governor up to a certain speed of the engine, and the quadrant arranged to correspond with the spring and governor action.

Presuming the parts to be assembled as described, the cam shaft operates the governor 14 continuouslyduring the operation of the engine to revolve the post 10, cap 22 and the governor arms; the cup 18 being revolved by the en agement of the ears 24 with theflange 18 and the ring 20 havin but slight active tendency, which is resiste by the spring 39. As the speed of the motor increases the governor members are revolved m re rapidly until, at a predetermined speed, the weights havebeen lifted by the cup centrifugal force sufiiciently to cause the arms 28 to press downwardly on the top of the cup, such downward pressure causing flange to engagethe loose rin and press same between the cup and post ange.

Under such engagement the friction inducing faces of the ring form a clutch between the loose cup and the revoluble members, causing the clutch to move with the gover nor and drawing the rod 31 forwardly against the tension of spring 39. a When the rod is drawn forwardly the valve in the carbureter is actuated to shut off the supply of vapor to the cylinders and reduce the power of the motor. As soon as the speed .has slackened, due to such decrease of power, the spring 39 draws the rod 31 back to open'the carbureter valve, and vapor is. again supplied to the cylinders to the former extent. By manipulation of the quadrant lever, the tension of the spring may be increased or decreased to lighten or increase the work of the governor, so thatthe speed at which the supply of fuel is influenced may be varied.

It is apparent that the mechanism described can be used in'connection with the ordinary controlled lever on the steering wheel. j
